Where can I find the employment information network of Shandong college graduates without contract certificate?

Does the subject want to consult "what is the non-signing certificate of Shandong University Graduate Employment Information Network"? Original ID card, original household registration book and unemployed certificate (unemployed) issued by the community where the permanent residence is located. Apply to the employment and social security institutions of the community neighborhood committees where the permanent residence is located, and the employment and social security institutions of the community neighborhood committees will investigate and verify, and the employment and social security institutions of the community neighborhood committees will issue unemployment certificates.
